>Description:
If you try to add a ipv6 proxy address like:

route add -inet6 2001:41d0:1:2ad2:1::/80 -interface gif0 -proxy

at line 734 of /usr/src/sbin/route/route.c


    if (proxy) {
-->     so_dst.sinarp.sin_other = SIN_PROXY;                                                                            
        flags |= RTF_ANNOUNCE;

`so_dst.sinarp.sin_other = SIN_PROXY;'

mangles the ipv6 address!

>How-To-Repeat:
route add -inet6 2001:41d0:1:2ad2:1::/80 -interface gif0 -proxy

>Fix:
For inet6, remove the offending line...
